Is a, 18W Phillips genie, sufficient artificial light for indoor growing of plants?
Not likely. The sun is giving them 1000Watts and that is what they are aiming for as a ‘full meal’ for the plants. If you are only getting 18Watts of energy in I can’t see how you get 100Watts out as you can’t make energy from nothing. However, even assuming 100 Watts that is going to be pretty low. I personally tried something like what you are doing here in Canada with a Mango tree from the Philippines. I used 3 x 75Watt grow lights. It was a very unhappy mango tree, it did grow–sort of. It grew very spindly and seemed to be ‘reaching’ for the light as it wasn’t enough so it ended up stretched and unattractive.
